Answer:
A centripetal force is a net force that acts on an object to keep it moving along a circular path
Answer:
(c). The two blocks end in a tie
Explanation:
the reason being the absence of any resistance offered to both of the blocks.
if the slope of the hill is for instance 60 deg.
then the acceleration in absence of any resistance is a= 9.81sin(60)
since the acceleration is same then both of the blocks will reach at the same instant
The band of stability curves upward at high atomic numbers due to the fact that excess of neutrons are required due to the repulsion between protons.
Atomic number is the number of protons. As the number of protons (atomic number) increase, the electrical repulsion force, due to the same sign of the protons inside the nucleus, becomes more dominant compared to the nuclear force attractions, then the nucleus needs more neutrons to gain stability.The presence of more neutrons decrease the density of protons which decreases the repulsion among them.
